The box is providedwith a screwfrom the chamber 27 and passingit back to plug l2, which closes an opening employed the chamber 26. Aconstruction of pump suited for this purpose is illustrated in Figs. 5and 6, in which it will be seen that the pin or axle 2O of the roller 19is extended into the body of a pump 36 and carries the arms 37 of same,the inlet-pipe 3S of the pump passing into the waste-oil chamber Q7,while the outlet-pipe 39 delivers into the chamber 2G, the pump beingoperated by the movement of the roller caused by the friction of theaxle 9 thereon.

In Fig. 7 is shown the arrangement employed when the axle-box is formedin top and bottom parts 1 2 instead of in one piece. Inthis case the toppart 2" is provided with a recess 40 for the vehicle-spring andspringbuckle and a recess 41, in which is fitted the bearing 14. It isalso provided with a projection 42, which iits into a recess in thebearing 14 in order to take the longitudinal thrust. On the side of thepartQ are projections 43 corresponding toprojections 44 or the bottompart 1, and through these projections pass bolts 45, said bolts beingprovided with the necessary nuts and with springs 13, which act to raisethe bottom portion l as the bearing wears, or, in other words, keeps itconcentric with the axle as the upperpart 2 falls with the wear of thebearing.

That we claim is* 1. In combination, the axle, a bearing above same, abox inelosing said bearing, means for supporting the bearing, springsexercising a pressure between a fixed part and the box, so that the boxis lifted and kept concentric with the axle as the bearing wears, meansforearrying the springs and means for counteract ing the upward tendencyof the springs, substantially as described.

2. In combination, the axle, 'a bearing above saine, a box inelosingsaid bearing, springs between the bearing Aand the box so that the boxis lifted and kept concentric with the axle as the bearing wears, meansfor guiding the box, means for supporting the bearing, and a frictionroller carried by the box on which the axle bears and adapted tocounteract the upward tendency of the springs, substantially asdescribed.

3. In combination,the axle, a bearing above same, a box adapted to holdoil, inelosing said bearing, means for carrying said box, springsadapted to raise said box and keep it concentric with the axle as thebearing wears, a friction roller carried by the box on which the axlebears, for counteracting the upward tendency of the springs, means forcarrying and guiding the springs, and means for guiding the box andsupporting the bearing, substantially as described.

4. In combination, the axle, abearing above same, a box adapted to holdoil inelosing said bearing, springs between the bearing and the box sothat the box is lifted and kept concentric with the axle, a saddle inwhich the box is guided, means for supporting the saddle, a lug carriedby the saddle and passing into the box for supporting the bearing afriction roller carried by the box on which the axle bears, and adaptedto counteract the upward tendency of the springs, a partition in the boxfor forming a waste oil chamber beneath same, and a stuffing box forpreventing the escape of oil from the axle box, substantially asdescribed.

5. In combination, the axle, a bearing above same, a box adapted to holdoil, inelosing said bearing, springs between the bearing and the box sothat the box is lifted and kept concentric with the axle, a saddle inwhich the box is guided, means for supporting the saddle, a lug carriedby the saddle and passing into the box for supporting the bearing andtakin g the longitudinal thrust, means carried by the bearing andengaging with said lug for keeping the bearing in position, a frictionroller Carried by the box on which the axle bears and adapted tocounteract the upward tendency of the springs, lugs for supporting thefriction roller, a spring Vfor keeping saine in contact with the end ofthe axle, a partition in the box for forming a waste oil chamber beneathsame, a stuffing box for preventing the escape of oil from the axle box,and a plate for covering the stuffing box substantially as described.

6. In combination, the axle, a bearing above same, a box adapted to holdoil inelosing said bearing,springs exercising a pressure between a fixedpart and the box so that the box is lifted and -kept concentric with theaxle as 'the bearing wears, a friction roller carried by the box onwhich theaxle bears for countei acting the upward tendency of thesprings, -a partition in the box for forming a waste oil chamber beneathsame, a stuffing box for preventing the esc-ape of oil from the axlebox, land a centrifugal pump operated by the revolving axle for liftingthe waste oil from its chamber back to the axle box, substantially asdescribed.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribin witnesses. X
